Showcase Pentax 50mm f/1.4 Super-Takumar M42 mount

Surprisingly, I couldn't find a thread for this lens. Mods, feel free to move this if I've missed something.

Putting this lens to work. I got a m42/k adapter and used that with a m43/k adapter - it works but is very loose. The lens came free several times. I suspect this was just the side-effect of two cheap adapters. I should try it on my K1000 to see if its the m43 or the m42 adaptor thats not quite up to spec.

Pretty good overall, as expected it was very soft wide open but stops down nicely
